IMPROVEM ENT IN PLOWS.

To all whom it may concern:

Be it known that I, JOSEPH J oNEs, of Wilmington, in the county of New Oastle and State of Delaware, have invented certain new `and useful Improvements in Plows Applicable `to Locomotive-Engines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification.

The greatest `difficulty met with in the employment of a locomotive to plowing land has been a suitable means of controlling the plows so that in an instant they may be thrown out of vor in work by the attendant on the machine. To accomplish this various devices have been employed, but none so simple as to be free from objection.

In plowing with steam it is not like that of an ordinary horse-team and single plow,whose handles are held by the workman, who, in prospect of an obstruction, can either stop the team or throw the plow out of the land; but in the use of steam a suitable mechanical contrivance must be substituted to prevent accident to the numerous plows, shares, or cultivators employed when a locomotive is used.

To enable others to construct and employ7 the mechanical means I have invented, I would describe them as follows, observing that in the construction ot'- the locomotive there is nothing peculiar from those in use:

A represents the bed or frame-work sus taining the plows, to be attached to the rear of a locomotive by suitable bolts or chains.

B is an Aupright sliding post, movinginways or guides connected with the bed. On its side is a rack, ci. In addition to the guides are rollers b, placed below the bed, and thereto attached for sustaining1 the lower end of B. The description of a single plow will answer for'any number employed in the gang. O is the beam; D, the mold-board; d, a colter; c,

a bolt connect-ing the post B with the rear end of the beam.

E is a draw-bar or upright attached to the front end of said beam.

F is a handlever,whose fulcrum is at g, and whose ofce is that of raising the front end of the plow-beam.

f j' are pinions meshinginto and moving the racks a a.

his an intermediate or connecting pinion mountedl on an axis capable of being 4thrown into orout of gear with pinions ff.

Kis a master-wheelmeshiug at all times with pinionsfj.

His a hand-lever socketed in the shaft o, which carries the pinion j'. When this lever is thrown down, as seen in the drawings, the plows will be thrown into the soil; but, as shown at H', the rear of the plow will be raised and out of work. In the shaft carrying pinion h is a hand-lever, L, which, on the contrary, when down throws the connectingpinion out of mesh, but when up all the pinions are broughtin mesh, and as a consequence the plows may be all worked simultaneously.

M is a large rollerv sustaining the frame at a suitable height above the earth while the plows enter the soil. Itis swung on a frame provided with a handle, m, at the rear of the frame or bed A of the machine.

n u are bearing-racks. Through holes there in bolts are passed, in locking the plows to their work, by the handlevers being brought in contact with said bolts.

The mode ot' working the plows may be thus described: rlhe workman, standing on the frame A, lays hold with left hand on the lever F, and on the lever H with his right,(now supposingtheconnecting-pinion h to be thrown out of gear withff.) On depressing lever F and raising lever H two ofthe plows will be raised from the soil independent of the others. Should it be required that the whole gang be raisedsimultaneously, then the counecting-,pinion his brought in mesh with fj', and all the racks will be operated on at once.

Having described my improvement, what I' JOSEPH JONES.
